Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470360, here are decompositions:

7 + 31470353 = 31470360
23 + 31470337 = 31470360
37 + 31470323 = 31470360
67 + 31470293 = 31470360
101 + 31470259 = 31470360
137 + 31470223 = 31470360
139 + 31470221 = 31470360
151 + 31470209 = 31470360

Showing the first eight; more decompositions exist.
